COMBINED HEAT INSULATOR AND PROTECTOR FOR MILK BOTTLES AND THE LTKE.

Application filed November 2t), 1925. Serial No. 70,226.

My invention relates to wrappings for bottles, and has particular reference to a wrapping which is designed for primary application to baby bottles for the purpose of 5 keeping them warm.

It is an object of the invention to provide a bottle warmer of this character which will be extremely simple to manufacture, presenting a neat outward appearance, and very In efficient inoperation, particularly from the standpoint of heat insulation. Anotherob ject is'to provide a device which will lend itself readily to washing, whereby great efficiency from the standpoint of cleanliness and sanitation results.

A feature of my invention lies in constructing a device of this character in the form of a bag-like structure comprising only two essential elements, an outer casing, and

an inner padding and heat insulating element removably insertable within the casing.

More particularly, a preferred embodiment of my invention contemplates the provision of a double-Walled tubular structure 'within Which the padding element in the 'form of an integral piece is removably disposed.

Another feature of my invention lies in constructing the casing of one integral blank whereby thecost of manufacture will be reduced to a minimum; and in utilizing a blank substantially rectangular in shape, whereby the maximumnumber of blanks will be available from a minimum bolt of material.

In a preferred embodiment, the integral blank is shaped to form four adjacent sections of substantially equal areas, and by suitably doubling these sections upon themselves in a manner which will be more fully disclosed hereinafter, the final structure is produced.

Another feature lies in forming the integral padding element of a single piece of material, such as felt, similarly shaped substantially rectangularlyso that the cost of material will be reduced.

A particular feature of my invention lies in providing means associated with the two elements heretofore referred to for binding the entire deviceinto a snug embrace about the bottle; and in providing for this purpose binding tapes associated preferably with the casing in a manner which is extremely'eflicient and of pleasing appearance. More particularly, the inventi n con emplates providing an opening in the casing and a registering opening in the interposed padding element, and attaching the binding tapes within the assembled structure in a manner whereby they may be passed outwardly through said registering openings and thence encircled about the structure, so that they will not only hold the structure in place with reference to the bottle, but will retain the padding element in correct relative position within the casing.

A further feature of the invention lies in so constructing the bag that it will have at least one opening therein through which the bottle may be inserted and removed and preferably a second opening of such a size and so positioned as to permit the top of the bottle to project outwardly therethrough after insertion thereof. v

For the attainment of the foreging objects and such other objects as may hereinafter appear or be pointed out, I have illustrated one form of my invention in the accompanying drawings, in which:

Fig. 1 is a perspective view of the bag in assembled position and associated with a bottle; P

Fig. 2 is an elevational cross-section along the line 22 of Fig. 1;

Fig. 3 is a perspective elevational View taken at approximately right angles to Fig.

l and showing the opening through which the bottle is insertable, this opening being shown in distended position to reveal the interior of the bag;

Fig. 4 is a cross-sectional view taken along the line 4.-4 of Fig. 1;

Fig. 5 is a front view of the padding element;

Fig. 6 is a development of the casing element, illustrating the first few steps in its manufacture Fig. 7 is a view similar to Fig. 6 showing a subsequent step of manufacture; and

Fig. 8 is a perspective view of the casing element completely manufactured and ready for the insertion of the padding element.

Referring now to the drawings and particularly to Figs. 6 and 7 and 8, it will be seen that I shape a substantially rectangular blank of material 10 into four adjacent transverse sections 11, these sections being preferably produced 'by forming spaced notches 12 in one longitudinal edge 13 of the blank 10. I prefer also to scallop the other l g udinal, edge of the blank 10 to impart to each section 11 a convex edge 14 whereby the final shape of the completed structure will be more suitably adapted for use. The sections 11 are all substantially equal in area, and I prefer to provide a reinforcing strip 15 along the line of intersection between the inner sections 11, although the provision of this strip is optional and is not. essential. Along this last-i'nentioned line of intersection, and preferably midway thereof, I provide an opening 16, the purpose of which will be more clearly explained hereinafter. To each free transverse edge 17 of the blank 10 I attach a binding tape 18, preferably midway thereof so as to be aligned with the opening 16. I

The next step in the manufacture of the casing comprises doubling the outer sections 11 upon the respective adjacent sections in a manner clearly shown in Fig. 7, and attaching them thereto along all. edges except the free transverse edges 17 which carry the binding tapes 18. It will be understood that no stitching is required along the fold line 19. Itwill be noted that by making the stitches just referred to, a pocket is formed by each superposed pair of sections 11.

These pockets are then doubled upon themselves in the opposite direction, as clearly shown in Fig. 8, and they are attached to each other along one complete longitudinal edge, viz, the edge 14, and along only a portion of the opposite longitudinal edge, viz, along only the edges of the original notches 12. No stitches are made along the edge constituted by the fold lines 19, which now overlie each other; and no stitches are made along that portion of the original longitudinal edge 13 which lies between the original notches 12. It will be obvious that there is produced a doubled-walled tubular structure having an opening 20 in one side thereof (produced by the edges 19) and having a relatively smaller opening 21 in an adjacent side thereof. I

Referring now-to Fig. 5, I shape a padding element 22, comprising an integral piece of material, to constitute two adjacent sections which conform substantially to any two adjacent sections of the blank 10. More specifically, it will be noted that I have formed a notch 23 in one longitudinal edge '24 of the blank 22, and I have scalloped the other longitudinal edge 25 similarly to the edges 14. Along the line of intersection be tween the two sections constituted by the notch 23 of the scallops 25, and preferably midway thereof, I provide an opening 26 of substantially the same size as, and designed eventually to register with, the opening 16.

- This blank 22 is now inserted into the pockets formedwithin the tubular structure here- .inbefore described. It will be understood edges 19 whereby the opening 26 will regist'er with the opening 16. The entire structure is now turned inside out to conceal the numerous stitches which have been made in the casing element. By turning the structure inside out. the free transverse edges 17 will be concealed within the structure, as more fully disclosed in Fig. 3. The binding tapes 18 are then threaded outwardly through the registering openings 26 and 16, and the completed structure is then ready for use.

Referring now to Figs. 1, 2 and 4, it will be clearly understood that a bottle 28 may be inserted through the opening 20 by distending the opening slightly asshown in Fig. 3, and the opening 21 will permit the top 29 of the bottle to project outwardly therethrough. I prefer to make the entire structure of a length and width to closely embrace the standard baby bottle with the exception of the top thereof; but it will be understood that the device may be suitably designed for application to bottles or similar structures of varying sizes, depending upon requirements. I prefer to make the opening 20 of a length less than that of the bottle, yet sufficiently large to permit the bottle to be inserted therethrough; and I prefer to make the opening 21 of a size sufiicient to permit only the narrowed top 29 of the bottle to project therethrough.

The binding tapes 18 emerging from the opening 16 are made of a length sufiicientto permit them to be encircled about the entire structure, whereby the bag will be se curely tied about the bottle. It will be noted that in addition to keeping the opening 20 closed with the bottle securely held within the bag. the binding tapes will simultaneously retain the padding element in correct position by virtue of their passage through the opening 26.

It will thus be seen that I have constructed a device which is extremely efficient because of the fact that it fits snugly about the bottle, permitting only the end 29 thereof to project out; and because of the fact that the insertion and removal of the bottle is an extremely simple operation. It will be understood that the binding tapes 18 may be augmented by snap fasteners or the like, or they may be dispensed with altogether, and any other suitable means may then he provided for retaining the opening 20 closed. I prefer however, the construction which I have illustrated because of the efficient binding effect of the tapes 18 upon the entire structure and the padding element. and because of the neat appearance which is produced.

I prefer also to enclose the entire structure as herein illustrated and described within a third element. comprising a casing shaped substantially like an ordinary bag outwardly through said small-openin and provided with elastic means around the neck thereof to keep the latter closed. How ever, I have not illustrated this outside casing. because its use is optional and it does not form an essential portion of my assembled device.

It will be obvious that another advantageous feature of my construction lies in the fact that the bottle is effectually protected from damage. Bottles of this character are almost always constructed of glass, and the particular use to which these bottles are put renders the possibility of droppage very great. The padded outer casing constituted by my entire device serves as an eflicient protective covering which will prevent damage or breakage even under extremely rough treatment. r

The efliciency of the present device from the standpoint of cleanliness is particularl i to be noted. The removability of the patding element permits the outer casing to be readily replaced should it become soiled; and the outer casing is of such a construction and preferably made of a suitable material, so that it may be washed with great facility.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:
